the overGRound marathon/relay

the overGRound marathon/relay is a free, unofficial marathon (26.2 miles) and relay in Grand Rapids, Michigan, starting at 8 a.m. on October 25, 2026. Co-hosted by local running and fitness groups, it is built around grassroots inclusion: you can run solo, split the distance as a relay team or turn up to support. The route passes the city's main landmarks and finishes at Rosa Parks Circle, and the event is largely self-supported, with course signage and aid stations along the way.

Self-supported means you carry more of your own plan than at a big-city marathon, so rehearse your fueling on long runs and know where you will drink. All paces are welcome, which makes this a workable first marathon if you would rather not pay a large entry fee, and the relay is an easy way in for anyone not ready for the full distance. Making your own bib is part of the tradition.
